Random Simpsons thought: all that "the show's not worth watching anymore stuff" aside (or maybe just lingering in the background), at what point did jokes from the show stop becoming well-referenced in geek culture (if not pop culture at large)? I mean, I always see references to episodes throughout the 90s, and some in the 2000s as well. But when did it stop? What (specifically, even) was the most recent gag that stuck around, and everything past that sticks to the show only?
Stuff like this keeps me up at night sometimes, I tell ya.
